The lever 23 when thusactuated will in turn actuate a lever 3| carrying a pin 32 against aspring 33 to remove said pin from a recess in a notched hollow disc 34driven by a spring motor 34a therein connected to shaft 32 to therebyrelease said motor. In other words disc 34 and one end of spring 34a arefixed to shaft 32. This motor34a is provided with cams 35 and 33respectively, as shown in Fig. 6, which are driven in unison. Cam 35 iscut to provide the registration and-recording of the watchmans boxnumber, as will be hereinafter described in connection with Fig. 6. Themember I! and lever |3 are returned to the position shown about fifteenminutes before the point 21 on the cam reaches the free end of the lever23, a pin- In on said cam engaging. a pin23 on said member.

If the watchman desires to transmits firealarm he-manually operates ahandle 31 to rotate a shaft 33 provided with a small cam 33 whichoperates a bell crank lever 4| on the plate 3 to likewise actuate thelever 3| to. release the motor 34a. The cam 35 is cut to provide 1 thefire signal and the shaft 33 is provided with an additional cam 40. Thiscam 43 normally renders a lever 42 pivotally mounted on plate |3ainoperla tive to respond to the configurations of the cam 33 but whenactuated by the fire handle 3l it permits the separation of contacts 43associated with said lever in accordance with said configurations tocorrespondingly control a switch by means.

The mechanisms in the watchmens boxes are time-controlled from thesubscribers oflice, a

master clock therein being provided with cams 5| and 52 (Fig/8) injuxtaposition on a shaft 53 of the master clock which makes onerevolution per minute.- These cams are provided with drop positions 54and 55, respectively, the latter occurring at a slight time intervalbehind the former. so that 'apgoted lever 56 having an elec-'t'ricalcontact 51 t e gagement with a contact 53 on a second lever 53will be separated." These contacts-51 and 53 are as shown in Fig. 5 incircuit with a magnet 3| at each watchmans box whereby animpulse reonand riding on the camp 54 may be actuated to bring said' contact inen-ris delivered each minute to actuate an armature 32 on a bell crank leverprovided also with a hook- 1 shaped member 33 for advancing the gear 3one tooth per minute. The lever carrying the armsture 32 and member 53is provided with a yieldable pivot, it being pivoted on the free end ofa lever 64 and provided with a spring 35 yieldably drawing it toward thecenter oi' .the gear 3.' A spring pressed pawl 33 is provided to preventback-lash.

Since the master clock at the subscribers ofllce controls the entiresystem, means. are-provided to indicate failure of the master clock.This means is illustrated in Figs. 7 and 11'.v The pendulum 31 of themaster clock (not shown) is'prol5 vided with a trough-like proiection'33. A small pendulum 63 skips over-the. projection 33 with each swingbutshould 'the'pendulum 31 stop the pendulum 33 will engage in the troughjust prior to stoppage of thela'rg'e pendulum and be actuated, causing apivoted lever II to rise'andallow is pivoted weight 12 to drop andv keepsaid lever in the-up position. The lever 1| carries an insulated contact13 which when said. lever is in up position engages a similar contactI4. These a source of current 15 and a magnet 13 whereby when the latteris energized itwill actuate an armature 11 provided with a pin". The pin13' normallylocks a spring motor 13 and when the armature 1! is actuatedsaid motor is released."

The motor 13 is connected with suitable alarm 2 devices.

Means are provided to prevent over-windingoi the spring motor 34a by thewatchmanas' he auto,-
